Pizza Shop in Philadelphia has Hugely Successful Pay it Forward System

Philadelphia, known for it's cheese steak sandwiches is really showing it's brotherly love at this pizza joint. This pizza place will sell pizza by the slice for a dollar each, one day a person asked if they ever had any homeless people show up and ask food. They did so he offered a dollar to buy that person's meal.

That has since turned into 10,000 slices paid forward by other customers.
